1. General description

The 74AHC2G126 and 74AHCT2G126 are high-speed Si-gate CMOS devices. They provide a

dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the

output enable input (nOE). A LOW at nOE causes the output to assume a high-impedance OFFstate.

The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.

The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
